(01; its-+231) invention relates to a cleaning device.

An important objectofthe invention is to provide ag device of theabove-mentioned character 1 adapted for cleaning wall :paper, window shades, calcimined interiors, upholstery, rugs, and car pet's ofpile fabriciconstruction.

A further object of my invention is to provide'a' cleaning deviceofv the above-mentioned character of .such shape and construction as to enable the same to be quickly and convenientlyv used in a variety ofpositions; to! reach inaccessible-positions when operated either for close work with the hand gripping the handleferrule, orwhen projected on the handle of desired length.

A further object of the invention is to provide means whereby the cleaning element may be use'dwith all sides of substantially equal dimening capacity of the cleaning element isimaterially increasedand its lifegreatly prolonged 1 In the accompanying drawing forming a part of. this specification, and. in which. like numerals arexemployed to designate like parts throughout the same, I .-Figure1is a plan view of the device, with the cleaning element removed, the holdingelements being'shifted'to the open'position, l.

Figurefi is'a fragmentary planview of the'de- 'vice, with theholding element in-the closed posi-J- I In the drawing, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral-l"designatesasbody,

lfig-having' ends it extending into the sleeves or knuckles II, and pivotallymounted therein. The u shaped extensions I'Sare'a'rran'ged at thelcorhem of the head orbody portion Ill. The-numeral ll. designates-clamping rails, preferably in, the iormof channels having, their open sides ar-' ranged, inwardly. These. rails ,or channels are U-shaped in cross-sectionand their, sides 18 are 5 apertured for slidably receiving the ends it of the holding elements.

. The handle attaching means embodiesa pair -of.spaced plates l9,..havingbases 2E3, whichare I rigidly attached to the inner surface oithe head or body portion H], at its center.. Each plate 83 has inclinededgesffl, diverging inwardly, and

The handle connecting means further embodies a ferrule 23, carrying apair of apertured knuckles 24, forthe passage of a bolt 25, alsoextending through openings formed in the plates l This bolt 25 maybe provided with a winged .nntZS. I A spacing sleeve 2'! surrounds the bolt 25.and is arranged :between the plates i9; By adjusting the winged nut 26, :the ferrule may have free pivotal connection with the plates l9,I or. it may be clamped thereto inthe selected adjusted posi ion. The ierrule'receivesa handle 28, as shown.

' The-numeral 29 designates acleaning element which is rectangular and isin'the form of a sheet I or pad,and is preferably'made of sponge rubber of proper "qualityand porosity, although the cleaning element may be made of other suitable 30 material.

In; use, the holdingelements l2 are shifted to the. openposition, Figures 1, 2 and 4, and the cleaningele'ment' 29 is placed upon the *outer surface oi thehead or body portionit. One edge of the cleaning element is now ;passed inwa'rdly over the longitudinal edge of the head lathe edges or corners of the cleaning elementbeing pulled-through the extensions l5. The clampingj rail. or channel I1 is now shiftedinwa'rdly 40 so that it substantially contacts with the U- shaped ektensions 15; and the holding element 1.2. is now swung inwardly upon-itspivot, so that the edges offthefirail' or channel firmly engage ,thecleaningelement29, Figure 5." The side it 5,

of. theholding ele'mentwill 'slidealong the inelineedgesof-the 'plates i9,=.the body portion orhead I I0 and the holding element being slightly resilient, until the side l'3l springs into the notches '22,at which'tiine the holding elementis locked in the closed'position. 1 Both holding elements are-operated in a similar manner, and the reverse of .this operationkis employed" when it is desired toremove the cleaning element 29.4

When th'e holding elements" IZ are in the' inner by eliminating the possibility of the extensions l contactingwith the surface: being cleaned, and

scratching the same. With the cleaning element secured to the head or body portion llL such cleaning element may be conveniently rubbed. over the surface to be cleaned, either by grasping 1 the ferrule 23, or by engaging the handle 28.

, The action of the sponge rubber cleaning element, when moved over the surface to be cleaned,

is to erase and absorb the dust anddirt through the vacuum action of its pores or cells. In-cleaning heavy wall smudges, a back and forth and rotary motion of the device produces the best results. When the handle is thrown out to con-- tact Withone side, and the face of the cleaner is away from the. surface, the rollof the element may be eifectively applied in'cleaning corners and angles between walls and ceilings. .I'he cap of doors and window-frames maybe cleaned'by reaching up and letting the inside of one end of the cleaning element rest on the ledge, and. then drawing the device over the surfacewith either one or both side rolls-of the element .in contact.

It is to be understood that the form of my in-- vention herewith shown and described'isto be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts maybe resorted towithout departing from the spiritof the invention or the scope of the subjoined claims. f 1
